Characteristic analysis of core strength training method: Core strength training method is unique, and its principle is to create an unstable state similar to some sports in training, through exercise the core muscles can change this unstable state under the regulation of nerve, compared with the traditional strength training, the core strength training plays a very significant role in the core parts of the body muscle and ligament strength strengthening. Core strength training can effectively enhance the contraction force of the core parts of the body muscles and ligaments under the innervations, small body deep muscle groups of fixed, stability and transmission of energy function is strengthened, nerve to muscle at the mercy of the ability gets further improvement and promote the energy transmission, improve the efficiency of the muscles to do work. Core strength training pays attention to the coordination development of the corresponding muscle, especially in the group of abdomen, the back muscle training, increases the power level of practitioners faster; it makes the body power of local practice and whole practice combine, the development of large muscle strength training and development of the small muscles training also combine, so as to improve the overall strength coordination of human body, can enhance the stability of the spine and hip, help practitioners to maintain good body posture, and prevent from fatigue caused by neck, shoulder, waist and back pain and other symptoms.
The purpose of the study was to investigate the effect of Lezium exercises training for twelve week on selected physical fitness components of school girls aged 13 to 15 year. To achieve the purpose the investigation was carried out in the Narhar Kurundkar High School, Kautha, Nanded. Sixty girls (n=60), were randomly assigned in to two groups Exp.Gr. (Lezium) and Control groups each group consists of 30 students. After the pre-test with the AAHPERD Youth Physical fitness Test Battery, the Exp. Gr.Lezium underwent a training programme of selected Lezium exercises, the dependent variable were assessed before and after training period. Lezium training showed significant improve in Muscular strength (Dynamic) (CD=0.63, p<0.01)., Abdominal muscles strength (CD=0.64, p<0.01),agility (CD=0.63, p<0.01)Explosive strength of legs (CD=0.74, p<0.01), speed (CD=0.57, p<0.01), flexibility (CD=0.59, p<0.01),cardiovascular endurance (CD=0.66, p<0.01). Control group did not show any significant differences in all variables.
The results of this study should be interpreted within the context of its limitations. Since this was a cross-sectional study, we cannot draw any conclusions about the causal or directional nature of the associations of muscle mass and quality with RKOA; although considering the lack of association between abdominal muscles and knee pain, it is unlikely that the observed association between the paraspinal muscles and RKOA was merely a consequence of knee pain. Moreover, although thigh/quadriceps muscle mass/strength is a well-known risk/protective factor for RKOA, we did not assess this directly. However, we did use DEXA to assess body composition and ASM, which is almost reflective of leg lean mass. We also did not assess abdominal muscle strength; however, muscle CT attenuation is a good index of muscular quality and strength. Our subjects were limited to medical checkup examinees and were more likely to be motivated for healthier lifestyle, and therefore, the selection bias also needs to be considered to generalize the findings. Finally, our definition of habitual exercise was not following the actual physical activity recommendations on a health perspective worldwide. 27
DOI: 10.4236/ojo.2018.88035 324 Open Journal of Orthopedics et al. reported that teaching nurses the proper lifting technique during patient transfer reduces lower back pain  . Proper et al . and Yuan et al . demon- strated that regular adherence to exercise and physical activity curbs the lower back pain among nurses  . Regular flexibility exercises stretch the tight para-spinal muscles of the lower back which, elongates muscle contractures, whilst facilitating the decompression of intervertebral discs and dissipating mus- cle spasms . Specific strengthening exercise will shorten laxed muscles and increase their strength and endurance when these muscles act as agonists, syner- gists, fixators and neutralizers to prevent unwanted muscle movement produc- ing lower back pain when performing strenuous physical tasks . Exercise therapists have being prescribing strengthening and stretching exercises to effec- tively dissipate lower back  .
A monocock structure of an airport bus is a very demanding product as regards its strength. With the application of the FEA (Finite Element Analysis ) method the allegedly critical points of the framework were determined; these especially occurred on the door frameworks. The experimental methods of measuring mechanical deformations confirmed the presumptions that maximum deformations measured at the points which were previously analysed with the FEA method. The driving regime with a maximum speed of 40 km/h in a circle with a minimum turning radius and a changeable regime of acceleration and braking proved critical. The measurements led to appropriate construction amendments, additional strengthening of the framework and other measures which fulfilled the required strength criteria.
This may be due to the polymers processed by injected molded technique are more flexible and ductile as expressed by Ippei H., that explain the higher results of flexure strength for heat cured acrylic in regarding to other experiment materials and why injected molded specimen didn’t fracture under the test 23 . The polycarbonate and injectable
Firstly set the machine by removing the error like set the machine at zero load and set fix or movable crosshead at proper position. After that create the new file in computer and add the type of material of specimen, shape of specimen ( Round or Rectangular ), gauge length ( the length which is under study or observation ), nature of testing ( tensile or compressive ) and which graph is required. Then placed the specimen in machine between the extensometer by hold the specimen at equal distance from both side (or at gauge length ). Now start the testing by apply the increasing load on the specimen, extensometer automatically record the deformation in gauge length. During this graph is prepare between the load vs displacement up to break point of specimen by the software and record in memory. Than save the graph, ultimate strength, elongation etc. This process is execute on every specimen and take the average response of 5 identical specimen. The observation of each type of specimen is given below.

Barnes (1969) studied the strength with which lemons were attached to their stems. He used tension, torsion, tension at angle, and shake resistance (Barnes, 1969). He used a special type of load cell to make his measurements. No significant difference was observed between tension and tension at angle for different varieties and in different climates. Detachment of fruit occurred when subjected to torsion or vibration forces.
ABSTRACT This review discusses the roles of the transforming growth factor-betas (TGF- β s) as part of a complex network that regulates the development and maintenance of the neuromuscular system. The actions of the TGF- β s often vary depending on which other growth factors are present, making it difficult to extrapolate results from in vitro experiments to the in vivo situation. A new approach has therefore been needed to understand the physiological functions of the TGF- β s. The behaviours (proliferation, fusion, apoptosis) of many of the cells in the neuromuscular system have a complex pattern which varies in space and time. The actions of growth factors in this system can thus be deduced based on how well their pattern of expression correlates with known cellular behaviours. Hypotheses based on this molecular anatomical evidence can then be further tested with genetically modified mice. From this type of evidence, we suggest that: (1) TGF- β 1 is an autocrine regulator of Schwann cells; (2) maternally-derived TGF- β 1 helps to suppress self and maternal immune attack; (3) TGF- β 2 regulates when and where myoblasts fuse to myotubes; (4) motoneuron survival is regulated by multiple sources of TGF- β s, with TGF- β 2 being the more important isoform. The concept of TGF- β 1 as a regulator of secondary myotube formation is not supported by either the location of the TGF- β 1 in developing muscles or by the phenotype of TGF- β 1 -/- mice. The review concludes with a discussion of whether all of these of postulated functions
In spite of the passage of time (Doliñski, 1995; Je¿owski, 1981, 1996; Pickett et al., 1969; Skubisz, 1982), efforts are still continued in the search for and improvement of a method for the estimation of stem and root lodging, especially with respect to cereal stalks (Berry et al., 2003a ). Those efforts resulted in indicating a varietal range of the moment of anchorage break (exceeding the limit of anchorage strength), of the values of the moment of stem failure, values of the moment of stem and plant base bending (Berry et al., 2003b). Among the methods used for the assessment of the mechanical properties of stems (rape) is the method based on absorption of X-ray radiation as determined on the basis of the parameter DOD determined with the densitometric method (Skubisz and Velikanov, 1994; 2000).
Extending the application of the strength-based dyadic approach to PwMCI would be even more appropriate, as their more preserved cognitive capacities would require a more facilitating rather than inhibiting social environment to encourage their active and self-directed role and social participation. Family caregivers become the key stake- holder who require the knowledge, skill, and attitude to create such a social context. Besides, supporting the PwMCI-caregiver dyads to better regulate the neuro-psy- chiatric symptoms, increase their awareness to the good qualities in the pre-morbid dyadic relationship and encou- rage effective use of previously established interpersonal skills are important to foster constructive dyadic relation- ship building. 6,14 Such relational quality is considered as highly desirable to facilitate effective coping with the life challenges associated with MCI from a social interactional perspective. 6

165 As the swarm size increases, centre-of-mass movements are determined by a balance between two competing effects: namely averaging over more but larger fluctuations because insects behave as if they are more weakly bound when in larger swarms [Kelley and Ouellette 2013]. The results of preliminary numerical simulations (not shown) suggest that the latter outweighs the former and that consequently centre-of-mass movements and so tensile 170 strength increases with increasing swarm size. Insect swarms are therefore predicted to ‘solidify’ as they increase in size, making it harder to pull them apart. This new prediction could be tested in the laboratory by measuring tensile strength as a function of swarm size. If true, then it suggests that insect swarms effectively cool as they increase in size. Fire ants, on the other hand, which link their bodies to form dense aggregations, behave more like viscoelastic 175 fluids, becoming stiffer and more purely elastic as the density of the ants increases [Tennenbaum et al. 2016, Vernerey et al. 2018]. Active changes in group morphology in response to dynamic loads are also evident in dense tree-hanging clusters of honeybees [Peleg et al. 2018].

We express our gratitude and appreciation to Uganda Industrial Research Institute (UIRI)for allowing us use their specialized laboratory space and equipment while conducting all the investigations. Our special thanks goes to Mr. Ivan Kalega who helped with thetesting and analysis of the clay samples, firing of samples using the UIRI furnace and testing the strength of the fired clay samples in his laboratory. We also, thank him for linking us to the Mineralogy Division at Mintek where the chemical analysis using X-Ray Diffraction of the sample clay soil was done.
Figure 1. Theoretical predictions for swarm density profiles match data from numerical simulations. The swarms are being pulled away from their respective swarm markers (dashed-lines) and displaced towards the origin. The swarms therefore appear in tension with a tensile strength that increases as centre-of-mass movements increase. Predictions (solid line) obtained from equation (12) are shown for a = 0.8, b = 0.1 and B 0 = 1 with B 1 = 0.1 (left), 0.3 (middle) and 0.5 (right). Simulation data (●) were obtained from
The present study incorporates mix design based on the guidelines as per Indian Standard code IS 10262-2009. The nano-silica used is imported from a supplier. The use of any kind of admixture is strictly prohibited in the mix design. The water content has been kept constant to facilitate a better comparison for different samples. The compressive strength measurements are carried out.
Results: Statistical analysis revealed significant difference among the groups at P<0.05. Group 2 treated with EDTA, had the highest bond strength; 18.63±2.85 MPa in cervical specimens and 13.49±3.67 MPa in apical specimens. The cervical specimens of Groups 2 and 3 were signifi- cantly different than the apical specimens in the same group. Adhesive failure between cement and dentin was the main failure mode observed in all groups. Groups irrigated with EDTA showed cleaner dentin surface and better resin tag formation, while groups treated with NaOCl showed less resin tag formation and insufficient smear layer removal.

The pelvic floor muscles (PFMs) are composed of a set of skeletal muscles. The levator ani muscle forms the main structure and is composed of three muscles: pubococcygeus, iliococcygeus, and puborectalis. These muscles are responsible for providing support to the static and dynamic internal pelvic organs and for the closure of the urethral sphincter, allowing urinary and fecal continence. 1
Abstract:- In the present scenario, an alternate for clay bricks is fly-ash bricks which plays a key role in the construction of framed structures because of its less weight which will reduce the dead weight of the structure, due to its light weight concept and another advantage is low cost. Such fly ash bricks are not subject to load bearing structure because of its slight reduction in compressive strength compared with nominal clay brick. So majority of the fly ash bricks were used in the framed structures construction. In this study a concern to increase compression strength using coconut fibre is carried out, with this another proportion of replacement to the fly ash is done with rice husk ash. By varying the proportion of fibre and rice husk ash of 5% and 10%, with coconut fibre’s aspect ratio of 150, is mixed separately and also in the combined proportion of 5% and 10% of coconut fibre and rice husk ash. A comparison has been carried out for the normal brick to the fibre reinforced brick and fibre reinforced rice husk ash by replacing fly ash in brick. From the comparison the test result has shown a significant change in the compressive strength by the addition of coconut fibre than the addition of rice husk ash to the normal fly ash brick and also the test results showed significant changes in the water absorption quality and other properties of the fly ash brick.
